Following up on this weekend’s analysis of the first two presidential debates we added yesterday’s final debate to the analysis. General consensus among viewers and pundits alike seems to be that Romney performed better than expected in the first debate, and Obama performed better in the final two debates. Here’s why this may be:

Obama’s Style More Persuasive

Obama’s success may in no small part be due to his speech style which combines words emphasizing certainty, thinking, and causation, compared to Romney’s directness and more perceptual style. In other words, Obama is far more likely than Romney to use words related to thinking (cognition) such as “I know” or “I understand” rather than Romney’s more perceptual words “I feel” or “I see”. Perceptive words are often considered less scientific and more subjective than thinking words. Obama’s speech is also more likely to contain causation, in other words he is more likely to back statements up as indicated by increased use of terms like “effect”, “hence”, “because” or “results”.

Additionally, Obama’s higher certainty (terms like “never”, “always”, “sure” and “definitely”), can provide stronger and more convincing arguments and can help paint the speaker as an expert.

In regard to sentiment, as discussed in yesterday’s post, throughout the debates while both candidates seemed to use equal amounts of positive emotion in their speech, understandably perhaps, Romney was more likely to also use negative emotion (especially sadness in the first debate). This can serve as an implicit way of attacking your opponent.

However, Obama’s insistence on the use of more collectivist language (i.e. use of “we” rather than individualist “I”), seemed to serve him well in countering these attacks. While it was not always clear whether Obama’s “we” referred to himself, his team or the nation as a whole, speaking in this ‘voice of the nation’ style undoubtedly served him well and together with the more sophisticated (longer words) and thinking words in his speech, may have helped paint him as a responsible, more certain and expert steward of our nation.

[NOTE: Text analytics can be used to investigate some of the reasons why Obama seemed to perform better than Romney. Explaining the success of Obama or Romney in debates they are considered to have won is difficult because neither candidate changed style much across the debates. In a few instances they switched style slightly from debate to debate, but more often their style categories were consistent across all three debates (including those lost). This emphasizes the fact that language use is something inherent to speakers and is quite subconscious. Rather than being a strategic choice, differences in style between debates may be a result from their reaction to debate-specific circumstances (questions from the moderator, behavior of the other candidate, etc.). Therefore this analysis focuses on Obama’s and Romney’s styles across all three debates.

The above speech characteristics are not the only indicative attributes enabling a candidate to win. However, since most likely a win is a combination of several language characteristics appearing in some or all debates (plus other non-linguistic issues including facial expressions, candidate’s general appeal to the public, their political affiliation and issue position) we can assume that some of these categories played a role in contributing to the success in the debates.]
